SCREEN-DOOR ATTACHMENT.

Application filed April 16, 1915.

To all whom it may com com:

Be it known that I, BENTON MOORE, a citizen of the United States, residing at Cherryvale, in the county of Montgomery and State of Kansas, haveinvented a new and useful Screen-Door Attachment, of which the following is a specification.

The device forming the subject matter of this application is adapted to be employed for locking doors, and particularly screen doors, in a closed position.

The invention aims to provide a novel mechanism which will hold the door latched, or at the will of an operator, hold the door positively locked.

Specifically, the invention aims to improve the construction of the locking memher and, to provide means for controlling the locking member so that interengaging elements on the locking member and the keeper will be maintained incoacting relation, to provide a novel form of latch, which, coacting in a novel manner with the locking member, holds the same positively engaged with the keeper and, generally, to improve and to enhance the utility of devices of that type to which the present invention appertains.

With the above and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawing :Figure 1 shows the invention in elevation, parts of the casing being removed, the keeper and the locking member being in the positions which they will assume before an interlocking relation therebetween is brought about; Fig. 2 isan elevation, parts of the casing being broken away, the keeper and the looking member being shown in latched relation; Fig. 3 is an elevation, parts of the casing being broken away, the keeper, the locking member and the latch being in the positions which they will assume-when a positive locking operation has been brought about; Fig. 4 is an end elevation of the casing; Fig. 5 is Specification of Letters Patent.

a view similar to Fig. 2 but showing a slightly modified form of the invention.

In the accompanyingdrawings, there is shown a door jamb 1 and a door 2'coacting with the door jamb. 'The door jamb 1 carries a supporting structure in the form of a casing 3 which may be closed by a lid 4, the same having been broken away in the drawings. In Figs. 1, 2 and 3 of the drawings,

the door 2 is equipped with a keeper 5 provided with a shoulder 6.

Disposed within the casing 3 is a locking member 7 having a shoulder 8 adapted to coact with the shoulder 6 on the keeper 5, an intermediate projection 9 upon its upper edge, and a lug '10 upon its upper edge and at its rear end. The locking member 7 is equipped with a slot 11 through which passes a securing element 12 mounted in the casing 3, the construction being such that the locking member 7 may tilt on the securing element 12 and have a longitudinal or translatory movement thereon.

A dog 14 is provided, the same being supported on a pivot element 15 carried by the casing 3. A stud 16 upstands from the dog 14 and a stud 17 depends from the top of the casing 1, these studs receiving the ends of a compression spring 18 abutting against the upper edge of the dog 14 and against the top of the casing. The invention comprises a latch 19 mounted to swing on a pivot element 20 carried by the casing 3. Projecting from the latch 19 is a finger 21 which may be slightly resilient, the finger passing outwardly through a slot 19 formed, as shown in Fig. 4, in one end of the casing 3 one edge 23 of the slot 22 being inclined as clearly shown in the figure above mentioned. i When the parts of the device are arranged as shown in Fig. 1, the free end of the latch '19 is uplifted, and the resilient finger 21 bears against the inclined edge 23015 the slot 22 in the end of the casing 3, the latch thus being upheld as shown in Figs. l2. The securing element 12 lies at the left hand end of the slot 11 in the locking member 7, the right hand end of the locking member 7 rests on the bottom of the casing 3, and the pivotally mounted dog 24 rests, under the action of the spring 18, on the projection 9. WVhen the door 2 is swung to closed position, the end of the keeper 5 passes beneath the dog 14 and strikes the right hand edge of the projection 9. Thereupon the looking member 7 moves bodily to the left and tilts on the securing element 12. By this operation, the interengaging elements represented by the shoulder 6 onthe keeper 5 and the shoulder 8 on the locking member 7 are brought into engagement, as clearly shown in Fig. 2. At the same time, the dog 19 is swung downwardly, so that the same coacts with the lug 10 on the locking member 7. The parts then appear as shown in Fig. 3,,and it will be seen that the door 2 cannot be. pulled into an open position.

- It is to be noted at this point that the sliding of locking member 7 to the left from the position of Fig. 1 to the position of Fig. 2 causes twooper ations to take place. First, the dog 14 is engaged with the right hand edge of the projection 9, and secondly, the lug l0 is moved far enough to the left so that it may be engaged by the latch 19 when the latter swings downwardly.

, In the modification shown in Fig. 5, the parts remain substantially ashereinbefore described. Parts previously alluded to are designated by reference characters formerly used, withthe sufIiX a. In Fig. 5 of the drawings, a recess 2 1 is formed in the door 2 and in the recess 24: is mounted a pivot element 25 supporting the keeper 5, the keeper resting. on the door2 at the lower edge 2670f the recess 24, so that the free end of the keeper cannot swing downwardly beyond a predetermined point. The keeper thus is so arranged that'it will coact with I the locking member 7 after the manner of Figs. land 2. The lug 10 on the locking member .7 or the latch 19 is prolonged, so that when the parts are in the latched condition of Fig. 5, the end of the latch 19 rests on the lug 10 In this form of the invention, the finger 21 moves freely in the end of the casing 3 and the structure 23 of Fig. .4 is not resorted to.

If it is desired to lock the member 7 positively, when the parts are disposed as shown in Fig. 5, the free end of the latch 19. is forced downwardly by means of the finger 21 'until the free end of the latch engages in front of the lug 10 During this 7 operation, the right handend "of the locking member 7 tilts upwardly to a slight extent, both the keeper 5* and the dog 11 yielding to permit such an operation.

Having thus described the invention, what is claimed is 1. In a device of the class described, a locking member mounted for tilting movement and for translatory movement and having a projection; a keeper, the keeper and the locking member having interlocking elements; and a yieldably actuated dog coacting with the projection; the keeper engaging the locking member thereby to impart tilting and translatory movement thereto, the tilting movement serving to bring the interlocking elements into engagement, and the translatory movement causing the dog to engage with the projection, thereby to maintain the interlocking elements yieldably interengaged.

2. In a device of the class described, a locking member mounted for tilting movement and for translatory movement; a keeper engaging the locking member to impart tilting movement and translatory movement thereto, the keeper and the locking member having interlocking elements which coact when the locking member is tilted; and a movable latch engaging the locking member to hold the interlocking elements positively engaged, the translatory movement of the locking member serving to position the same in the path of the latch.

3. In a device of the class described, a locking member mounted for tilting movement and for translatory movement, the locking member having a projection; a yieldably actuated dog resting on the proj ection; a keeper engaging the locking member to impart tilting movement and translatory movement thereto, the keeper and the locking member having interlocking elements which coact when the locking member is tilted; and a movable latch engaging the locking member to hold the interlocking elements positively engaged, the translatory movement of the locking member causing the dog to engage with the projection thereby to hold said interlocking elements yieldably interengaged and the translatory movement of the locking member serving to dispose the locking member in the path of the latch.

4. In a device of the class described, a locking member mounted for translatory movement and for tilting movement and provided with a lug; a keeper engaging the locking member to impart translatory and tilting movement thereto, the keeper and the locking member having interlocking elements which coact when the locking member is tilted; and a movable latch, the translatory movement of the locking member serving to dispose the lug in supporting relation to the latch, the locking member being movable under the action of the keeper to permit the latch to engage With the lug, thereby to hold the interlocking elements positively interengaged.

5. In a device of the class described, a locking member mounted for translatory movement and for tilting movement, the locking member being provided With a lug and With a projection; a pivotally mounted dog coacting With the projection; a keeper engaging the locking member to impart translatory and tilting movement thereto, the keeper and the locking member having interlocking elements Which coact when the locking member is tilted; and a movable latch, the translatory movement of the locking member serving to dispose the lug in supporting relation to the latch and serving to cause the dog to engage With the projection, thereby to hold the interlocking ele ments yieldably interei'igaged, the locking member being movable under the action of the keeper to permit the latch to interlock With the lug.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two Witnesses.
